FeaturesNXShield-Dx attaches directly to an Arduino Duemilanove or Uno, and it has headers to connect other shields on top.
It allows you to connect upto 4 NXT/EV3 motors, and 4 NXT Sensors, and program for them through Arduino sketch.
You can also attach upto 6 RC Servo motors to NXShield-D.
It also provides ports for I2C devices.

Programming for NXShield is on Arduino, using usual Arduino C/C++ programming environment.

Works with following boards:

Arduino Uno, Uno R3

Arduino Duemilanove

chipKIT Uno32

Connecting with Arduino
NXShield directly mates with Arduino. (it has rows of pins that will engage in your Arduino directly).

Shield AttachedYou can use most of the shields designed for Arduino Uno and/or Duemilanove with NXShield-Dx.
Just attach your shield over the NXShield-Dx (on top).
